Question

Rick ran 7.1 miles on Monday, 3.5 miles on Tuesday, 9 miles on Wednesday, and 5.8 miles on Thursday. How many miles does he need to run on Friday to average 6 miles per run?

Answer 1

There's 5 days so 6 times 5
$6 \times 5 = 30$

Then subtract,
$30 - 7.1 - 3.5 - 9 - 5.8 = 4.6$

Answer : He needs to run 4.6 miles on Friday.
